Doesn't Nick Fury have a rule against inter-superhero-organization romance?

There have been several pics surfacing from the set of "Captain America: The Winter Soldier" over the past several weeks, including looks at Cap in his upgraded costume and that of his nemesis, the black-clad Winter Soldier (Sebastian Stan). The most intriguing pic so far, however, hints at the celebrated war hero finally getting a little action that doesn't involve punching and throwing his shield at things.

And with Black Widow, at that! The new set pic features Steve Rogers (Chris Evans) and Natasha Romanoff (Scarlett Johansson) locking lips on what appears to be an escalator (hot!). The Avengers teammates are out of their superhero get-ups with Natasha wearing a hoodie and Rogers in a baseball cap — both good ways to semi-conceal one's identity, which seems in tune with the reported '70s-esque conspiracy thriller vibe of the sequel.

The only romance Captain America has had so far in the onscreen Marvel Universe is an affectionate though rather chaste relationship with his World War II-era sweetie, Peggy Carter (Hayley Atwell). The couple shared only a quick peck on the lips before Cap had his final battle with Red Skull (Hugo Weaving) in the hero's first stand-alone adventure, "Captain America: The First Avenger" (2011).

A smooch from Black Widow in "The Winter Soldier" is somewhat surprising, as there was no hint of a little something-something going on between the two in "Marvel's The Avengers" (2012). If anything, Natasha seemed to share a deep connection with Clint Barton/Hawkeye (Jeremy Renner), which had many thinking that they'd be romantically involved in some future Marvel movie.

Or, as E! Online points out, it could be a trap of some sort ... she is named Black Widow, after all. Natasha does have a romantic history with Bucky Barnes, aka the Winter Soldier, in the comics, so maybe we're looking at the beginnings of a very dangerous love triangle.

"Captain America: The Winter Soldier" hits theaters on April 4 next year.
